A Suffolk County grand jury has indicted Olivia Mora, 36, for manslaughter for the death of Briana Rosales, 7, on an Olney Street sidewalk last November.

Mora faces up to 20 years in prison if convicted on the charges of manslaughter by motor vehicle, motor vehicle homicide while operating under the influence, assault and battery with a dangerous weapon, operating under the influence causing serious bodily injury and leaving the scene of an accident causing personal injury, the Suffolk County District Attorney's office says.

In a statement, the DA's office gave this account of the Nov. 26 incident:

"The victims were walking on Olney Street when they were struck by Mora's Chevrolet Tahoe. Evidence suggests the sport-utility vehicle was going over the speed limit when it struck a parked car, jumped the curb, hit a fire hydrant, then collided with the victims. Morales was mortally injured and succumbed to her injuries at Boston Medical Center. Her mother, 26 and a resident of Dorchester, suffered life-threatening injuries but survived."

The DA's office says Mora is a Dorchester resident, although she was carrying a California license and driving a car registered in New Hampshire when arrested.
